Watch every anime I ever meant to watch/re-watch!!! Read everything! Listen to loads of music (Find new bands/get new music)! Make a manga! Draw and write loads! Be super lazy and Crunchy-Roll to anime heaven!
I have a big list for this summer.

Finishing my master's degree! Re-watching Kuroko's Basketball once I finally come to accept that nothing else can fill the void left in my heart. That said, Free! Eternal Summer will help. Also, seeing my high school friends!
